Japan Has Been Beating the Heat for Over 140 Years

If you've ever stepped outside in Georgia during July, you know the kind of heat that makes you rethink every life decision. Now imagine that same sticky, humid air across an entire island nation. Japan's summers are legendary for their intensity, and over the centuries, Japanese culture has developed an incredible lineup of beverages to cope.

That ingenuity has caught the world's attention. Japan's non-alcoholic beverage market hit $40.5 billion in 2025, and global demand for these drinks keeps climbing. There's something here for everyone, from iconic festival sodas to centuries-old household remedies.

Here at Tomato Japanese Grocery, we've been stocking these summer favorites for our Marietta community for over 20 years. Every summer, we watch them fly off the shelves. We're excited to share them with Japanese food lovers across the country. Here are seven beverages that will change the way you cool down this summer.

Ramune — The Marble Bottle That Pops Open Summer

Ramune has one of the most surprising origin stories in the beverage world. In 1884, a Scottish pharmacist named Alexander Cameron Sim introduced it in Kobe, Japan, originally marketing it as a cholera remedy inspired by Western lemonade. The name "Ramune" is simply the Japanese phonetic pronunciation of "lemonade," and it stuck.

What really sets Ramune apart is its bottle. Based on the Codd-neck design pioneered by British inventor Hiram Codd in the 1870s, each bottle contains a glass marble sealed in place by carbonation pressure. To open it, place the included plastic plunger on top of the marble, press down firmly with the heel of your palm, and push the marble into the neck of the bottle. You'll hear a satisfying "pop" as the carbonation releases. Hold the bottle upright for a moment to let the fizz settle, then sip away.

In 2025, Hata Ramune revived its all-glass bottle as the "HATA PREMIUM" edition, complete with a wooden ball stopper. It's a beautiful nod to Shōwa-era nostalgia that's resonating with younger generations both in Japan and abroad.

The flavor range is wild. You'll find classic lemon-lime and melon alongside novelty options like takoyaki, wasabi, curry, and yogurt. Collectors love hunting down the strangest ones. And if you're an anime fan, you've almost certainly seen Ramune at a matsuri (festival) scene. It's become a recognizable symbol of Japanese summer for fans worldwide. Fun fact: May 4th is officially "Ramune Day" in Japan, celebrating this drink's deep cultural significance.

Calpico — The Milky Way in a Bottle

Calpico (known as Calpis in Japan) holds a special place in Japanese beverage history. Released on July 7, 1919, the same date as the Tanabata Star Festival, it became the world's first commercially produced lactic acid beverage. That Tanabata connection runs deep: the iconic blue-and-white polka dot packaging was designed to represent the Milky Way galaxy. The colors were inverted in 1953, switching from white dots on blue to the blue-on-white design we know today.

If you've ever wondered about the name difference, here's the story. In Japan, it's called Calpis (カルピス), but the name was changed to Calpico for North American markets to avoid an unfortunate English slang association. You'll still see the Japanese katakana カルピス printed on the packaging.

Calpico comes in two main formats. The concentrate version is meant to be diluted with cold water or milk to your preferred strength. The ready-to-drink bottles and cans are perfect for grabbing on the go. Calpico Soda, the carbonated version first released in 1974, has its own loyal following and works brilliantly as a cocktail mixer with shochu, sake, or vodka.

The flavor lineup is impressive: strawberry, lemon, grape, melon, mango, matcha, and aloe, among others. When the pre-diluted Calpis Water launched in 1991, 20.5 million cases sold in the first year alone. That kind of demand speaks for itself. This is a drink Japan genuinely loves, and once you try it, you'll understand why.

Mugicha — Japan's Ancient Caffeine-Free Summer Tea

Mugicha, or roasted barley tea, is the quiet hero of Japanese summers. It's caffeine-free, sugar-free, and calorie-free, and it has been a household staple since at least the Heian Era (794–1185 AD). Walk into any Japanese home, school, restaurant, or hospital during summer and you'll likely find a pitcher of cold mugicha in the fridge.

Beyond its clean, toasty flavor, mugicha offers some interesting functional benefits. It naturally contains melatonin and the amino acid tryptophan, both of which are believed to support better sleep quality. For a summer drink, that's a remarkably thoughtful bonus.

Preparing mugicha at home is simple. Drop a mugicha tea bag into a pitcher of cold water and let it steep in the refrigerator overnight. You can also brew it hot and chill it if you prefer a stronger flavor. Either way, it's ready when you are.

Mugicha is ideal for kids, pregnant women, and anyone looking to cut caffeine without sacrificing flavor. It fits perfectly into the growing trend toward low-sugar, unsweetened, and functional beverages that gained momentum through 2025 and into 2026.

Pocari Sweat — Japan's Answer to Summer Dehydration

The name might raise an eyebrow, but Pocari Sweat is serious about hydration. This Japanese isotonic sports drink is formulated to replenish the electrolytes and minerals your body loses through sweat. It's non-carbonated with a mild, slightly citrusy taste that goes down easy even in extreme heat.

In Japan, Pocari Sweat is widely recommended during the brutally humid summer months. If you live in Georgia, you know exactly the kind of weather we're talking about. This drink was practically made for Southern summers too.

Japan's functional drinks market reached $8.49 billion in 2024 and is projected to grow to $20.19 billion by 2033, with sports drinks as the fastest-growing segment. Pocari Sweat sits right at the center of that growth. Compared to many American sports drinks, it's a lower-sugar option that focuses on genuine rehydration over flashy marketing.

You can find Pocari Sweat at Tomato Japanese Grocery, whether you visit us in Marietta or order online for delivery anywhere in the US.

Melon Soda, Calpico Soda & Two More Refreshers Worth Knowing

Melon Soda (Melon Cream Soda): That bright, almost neon green color is unmistakable. Melon soda is sweet, fun, and a staple at Japanese festivals and fast-food chains. The classic way to serve it: top a tall glass of melon soda with a scoop of vanilla ice cream for a melon cream soda float. It's a visual showstopper and a favorite among fans of J-pop culture and anime.

Calpico Soda: We mentioned it earlier, but it deserves its own spotlight. The carbonated version of Calpico has a lighter, fizzier profile than the original, and it's become a go-to cocktail mixer. Try it with shochu, sake, or vodka for a refreshing summer drink with a tangy twist.

Mitsuya Cider: Don't let the name fool you; this isn't apple cider. Mitsuya Cider is Japan's classic clear carbonated soft drink, often compared to ginger ale but lighter and sweeter. It's been a beloved staple for generations.

DIY Calpico Float: Pour Calpico Soda into a tall glass, add a scoop of vanilla ice cream, and finish with a splash of lemon juice. It's simple, photogenic, and perfect for recreating that "Japanese convenience store at home" aesthetic that's been trending on social media.

Here's a quick guide to help you pick your perfect match:
